GRAVITY DUMPlNGi-CAR.

SPECIFICATION forming part of Letters Patent No. 794,485, dated July 11, 1905.

Application filed June 8, 1904. Serial No. 211.631.

To all whom it may concern.-

Be it known that we, MOKINLEY BOYLE and CLYDE E.USTIOK, citizens of the United States, residing at New York city, county and State of New York, have invented new and useful Improvements in Gravity Dumping-Cars, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to the type of dumping-car in which the load may be dumped or discharged to either of two opposite sides of the car; and the particular objects of the invention are to construct a comparatively simple form of such a car from which the load may be quickly and cleanly discharged and in the construction of which steel or other suitable metal may be entirely used, thereby making a more durable and inexpensive car.

W itli these and other objects in view our invention consists in the various novel and peculiar arrangements and combinations of the several different parts of the apparatus, all as hereinafter fully described and then pointed out in the claims.

NVe have illustrated a type of our invention in the accompanyingdrawings, wherein Figure 1 is a side view of a dumping-car embodying our improvements and with the parts adjusted in closed position for retaining the load. Fig. 2 is an end view of the car with one-half thereof in vertical transverse section and with the parts shown in the same relations as Fig. 1 to retain the load. Fig. 8 is an enlarged transverse vertical section showing in detail the peculiar hinge at the lower edge of theswinging'central floor-section, which may be set to one side or the other to cooperate with one or the other of the two inclines of the discharging-floor. Figs. 4 and 5 are enlarged detail views of parts of the releasable locking means for retaining the swinging side doors closed on their respective inclines of the discharging-floor. Fig. 6 is a plan view of an end portion of the central swinging floor-section with one of the sides shown. as broken away to show a stay-bar I upon the interior.

Fig. 7 is an end view of this adjustable floor-section. Fig. 8 is a somewhat enlarged sectional view of a portion of the adjustable floor-section, the plane of the section being indicated by the line 8 8, Fig. 7.

Referring to the drawings, in which like figures of reference indicate like parts throughout, 1 designates a suitable truck, upon which the bottom frame 2 of the car is mounted and which in turn sustains the car-body. The body comprises four main uprights 3, placed one at each corner and resting upon one of the cross-pieces 2 of the bottom frame and inclined outwardly from the bottom toward the top of the car, but being vertical in relation to the end of the car. These main uprights 3 are secured at the top at each end of the car by suitable angles 4, and they are connected longitudinally by angle-irons 5. The fixed side of the car comprises ashort section 6 and a downwardly and inwardly inclined fixed part 7, which extends a suitable distance inwardly upon each side and substantially on the same plane of inclination as the downward inclination of the discharging-floor 8 and 9 upon the opposite side of the car, as hereinafter described. The fixed upper part 7, like the part 6, is made of suitable sheetsteel, and the two parts are secured together by a row of rivets, (indicated at 10,) the inclined side 7 being reinforced by the angleirons 11.' r

The respective ends of the car-body each comprise a sheet-metal body or plate 12, which has its upper and lower ends riveted to the top bar 4: and one of the bottom cross-pieces 2, respectively, and completely covers the end of the car, with the exception of the cut-away places 13 at the side edges thereof, and around one edge of which cut-away part the end 7 a of the side 7 is bent and riveted, while the other inclined edge of the cut-away part 13 is supported and braced by an angle-iron 14:, extending from one of the lower corners of the end plate 12 and upwardly and inwardly to a suitable point on the top bar 4:. These end plates 12 are also braced by vertical angleirons 14:, which are riveted thereto at suitable intervals.

The discharging-floor of the car comprises two oppositely and downwardly inclined parts 8 and 9, which are alike, and each of the same is made of sheet-steel extending the length of,

the car-body and from substantially the center line of the car downwardly to a point at the lower side of the car to a suitable point for discharging the material therefrom. A channel-plate extends along underneath the discharging-floor,near the lower end thereof, for supporting the same, and the body of this part is made sufficiently rigid by strengthening ribs or pieces 16, secured to the under side thereof at suitable intervals. The upper ends of the two discharging-floors 8 and 9 form an apex, along which longitudinally extends a groove which constitutes the socket or part 17 of the peculiar hinge-joint of the adjustable swinging floor-section 18. (See particularly Fig. 7 3.) This hinge-socket 17 is formed along the top of a sheet-metal body 19,the sides of which are downwardly and outwardly inclined to conform to the inclination of the discharging floor-section 8 and 9 and extend thence vertically downwardly. and is supported from beneath by a series of yok'es or brackets 20, which are shaped to fit beneath the metal body 19, and these yokes are preferably castings to which the sheet-metal body is riveted, the yokes 20 being supported by vertical members 21, between which and the yokes the downward portion of the metal body 19 is interposed, and the three parts are riveted together, as shown in Fig. 3. The upper ends of the vertical angle-irons or supporting members 21 are inclined to fit beneath the discharging-floors 8 and 9, and these supports 21 are each riveted at its lower end to the back of a channel-bar 22, which extends longitudinally of the car centrally thereof and is secured to the bottom frame 2 of the same. This construction provides a very strong and durable piece of mechanism and one in which there are practically no joints or seams over which the material is passed in dumping.

The adjustable swinging floor-section 18, which is hinged at its lower end to the apex of the inclines 8 and 9 of the discharging-floor, is the length of the car-body and is of a suitable width to reach and slightly overlap the lower end of either of the inclined fixed sides 7 at the upper part of the car-body and with each of which sides this section 18 forms practically the same plane when set against such side, the lower cooperating end of each of the sides 7 beingforrned with an offset or bend Tfor the purpose of making the two parts practically flush when they are placed together, as indicated in Fig. 2. Thus the swinging adjustable floor-section may be set or placed normally to cooperate with either one or the other of the inclined sides? and in thesame plane thereof, and under which con-,

dition the two said parts are substantially in the same plane with'the discharging-floor at the opposite side of the car, and each of said parts when the car is loaded serves to sustain the load.

The swinging floor-section which is located centrally of the oppositely-inclined discharging-floor is composed of two sheet-steel plates 18, which are placed together V-shaped and between the diverging ends of which is an iron bar 23, having the ends provided with hingepins 24, which are journaled in suitable sockets at the end of the floor-section 18. Between peculiar manner for the purposeof making the same self-cleaningin dislodging from the hinge-joint any dirt or foreign matter that may accumulate therein for the time being from the contents of the car. The back edge of the swinging section 18 is provided with a curved piece of sheet metal 26, between which and the flat side of the hinge-bar 23 is interposed a filling-piece27, of metal, and the ends of the back piece 26 are brought out flush with the sides 18 of the section. This back piece 26 has its outer surface formed on an arc the center of which is the center of motion of the hinge-pin 24:, the axis of which lies in the plane containing the two edges 28 of the hingesocket extending along the apex of the oppositely-inclined discharging-floors 8 and 9. The ends of the sheet-metal pieces 8 and 9 of the floor which project above the metal body 19 are curved on the same are as the socket 17 of such body, so that the entire surface of such socket lying between the edges 28 forms a semicircle, and when the section 18 is set to one side or the other its outer surface forms a practically continuous surface with the adjacent inclination of the discharging-floor and makes afiush joint therewith, which joint is dirt-proof, so that none of the contents of the car when loaded or in discharging can find its way into this joint. In case foreign matter should get within the groove or socket of the joint it would accumulate in the. space which is formed therein to one side, as indicated in the drawings, and it would at once be dis- L lodged whenever the floor-section is turned into the opposlte direction or angle, as in such case the back 27 of the swinging part would scrape such foreign matter from the socket and force it over the adjacent edge 28 thereof.

At each side of the car is a depending door 29, which is hinged at 30 to the under sideof the adjacent inclined side 7 These doors are eachmade of sheet-steel and extend the length of the car-body, being reinforced at suitable intervals with strips or angle-irons 31 and having the lower edge provided with reinforcing angle-irons 32, these angle-irons being all riveted to the metal sheet to form a rigid structure. The outer or free ends of the depending side doors 29 close inwardly against the adjacent inclination of the dischargingfloor 8 and 9 to retain the load at that point, and the depth or width of these doors may be varied, though we have shown them of such length that they close inwardly on their respective inclines without passing through vertical positions and making an acute angle with the inclination of the discharging-floor. This angle may be made less or greater, and the more acute it is the greater will be the capacity of the interior of the car-body at this point. Each of these depending side doors 29 is releasably locked when closed against its respective incline of the discharging-floor by means of a set of latches 33, which extend up through suitable openings in the surface of the incline and work in the guides 34., arranged beneath the incline. (See particularly Figs. 1 and 5.) These latches 33 are each provided with laterally-projecting pins 35, each of which passes through an elongated slot 36 in the end of an arm 37, which is made fast on a rock-shaft 38,

which is mounted in suitable bearings beneath the incline of the discharging-floor and extends the length of the car-body, with one end projecting beyond one end of the car-bod y, where it is provided with a hand-lever 39, having a locking-link 4:0 for holding the lever in position to maintain the latches in locking position, as shown in Fig. 2. When the swinging side door 29 is closed against its incline, the rock-shaft '38 is turned, by means of the hand-lever on the exterior of the car, in such a manner as to project the latches 33 and lock the door, and the hand-lever 39 is then itself locked by its link 40, which keeps the door closed securely. When it is desired to open the side door, the hand-lever 39 is ma nipulated so as to rock the shaft 38 in the opposite direction and withdraw the latches, thereby permitting the door to be opened by the loaditself gravitating down the incline, and thus the discharge of the load may be effected, and in this connection it is observed that only one of the side doors at a time acts to retain the load, and this is determined before loading the car by the requirement of the load having to be subsequently discharged from. one side or the other. In Fig. 2 the'arrangement of the various parts is shown when the load is to be discharged at the right-hand side of that figure, so that in this case the floor-section 18 is set to the left-hand side of the car. Under this condition the entire load in the car is sustained by the fixed sides 6 and 7 of the car-body, the floor-section 18, and the swinging door 29 (shown in dotted lines) at the opposite side of the car from where the floor-section 18 is adjusted, and the incline 9, against which the door 29 is closed.

In order to provide for positively swinging the side doors 29 open in dumping or discharging the load, there are provided the chains 41, each of which is connected to the back of each door 29, with its other end passing around a winding-shaft 42, mounted in suitable brackets 43, secured upon the uprights 3 of the car, one end of the winding-shaft being provided with a hand-wheel 44 secured thereto, the unwinding of the chain by the weight of the door being prevented by means of a ratchetwheel 15, secured upon the shaft 12, and a pawl 46, mounted on a fixed part and engaging the ratchet. To give a balanced action to the door-opening mechanism, we arrange two chains 41 for each door, one chain being near each end thereof, as shown in Fig. 1. After thelatches 33 are withdrawn to release the door the hand -wheel 44 may be turned to quickly pull the door open.

In the use of this construction of car, the load being sustained by the several respective parts above pointed out, the weight of the load tends to force open the door 29, which is located to the side of the car at which the load is to be discharged, so that upon this side door being released such weight of the load will act to force the door open, and the entire contents of the car may at once gravitate down the several inclined parts and be dumped from the inclined floor. Since,therefore,the weight of the load tends to force open the side door at the discharging side, such weight or gravity thereby serves to materially assist in discharging the contents of the car.

It will be noted that the discharging-inclines 8 and 9 of the floor, which extend downwardly in opposite directions toward the re spective sides of the car, may be inclined at any desired angle and that when this angle is changed the angle of the inwardly-inclined sides 7 at the upper part of the car are to'be' placed substantially in the same plane with its cooperating discharging-floor at the opposite side of the'car. This construction of the discharging-floor is found to be very eflicient to expedite the dumping of the load, and no manipulation of any part of this dischargingfioor is required in order to dump the load. The lower end of the inclines 8 and 9 of the discharging-floor may be extended to any suitable point at the side of the car, though we have shown it as projecting just slightly beyond the running-gear or truck 1, so that the load is dumped or discharged at a suitable distance beyond the side of the car without any of the contents becoming lodged in any parts of the apparatus.

The various described parts of the car herein set forth are made of suitable metal, so that the use of wood may be wholly dispensed with and a more durable and inexpensive car may thus be made.

We wish to be understood as not limiting our invention to the specific forms of the-various parts as herein set forth, as modifications may be made in such parts without, however, departing from the spirit of the inven tion.
